I have one of the double b 2 inch ones. When compared to some of the others it's reasonably priced but I have had a lot of trouble with the "special o-ring seal" not allowing rotation. It rusts up in their after using fertilizer and we are constantly having to pull it out, lube and clean it. Needs to be stainless. Nice reel but I cannot recommend for fertilizer. This post was just to provide info, not trying to knock their reel and for all I know they have changed the design by now, mines about 4 years old.
